本文针对产品寿命缩短抵消技术进步的问题，将减少一次性经济的政策建模为部门正向生产率冲击，研究其传导条件以在不降低消费者福祉、报酬和利润的前提下缩短工作时长
AI 中文摘要
约一个世纪前，凯恩斯预测，由于技术进步，如今的每周工作时长将缩短至15小时。但实际上，巨大的技术进步似乎被产品寿命的大幅缩短所抵消。从标准微观经济学视角看，这是低效的，因为为提供既定水平的产品服务，投入了超出必要的劳动力和物质资源。本文将旨在减少当前“一次性经济”的政策建模为某一经济部门的正向生产率冲击，研究该冲击向其他部门传导的条件，以在不降低消费者福祉、劳动报酬或利润的前提下缩短工作时长。为此，我们首先聚焦于一个简化的三部门模型
英文摘要
About a century ago, Keynes predicted that, thanks to technological progress, today's working week would be reduced to 15 hours. In practice, however, large technological gains seem to have been offset by a substantial shortening of product lifespans. From a standard microeconomic perspective, this is inefficient as more labour and material resources are employed than necessary to deliver a given level of product-provided services. In this paper, we model policies aimed at reducing the current 'throwaway economy' as inducing a positive productivity shock in one economic sector and examine the conditions under which this shock's propagation to other sectors can allow for a reduction in working time, without reducing consumers' well-being, labour compensation, or profits. To this purpose, we first focus on a stylized three sector
